SPECIFICATION forming part of LettersPatent No. 61 1,031, dated September 2.0, 1898. Application filed March 19, 1897. Serial No. 628,331. (No model.)

To @ZZ whom t naa/y concer/1,.-

Be it known that I, OSCAR FRorsoHEE, a

citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certainnewand usefulImprovementinWindows, of which the following is a specification, reference being had to the accompanying drawings.

This improvement relates to that class of windows which are provided with sashes designed to slide vertically when in their normal condition, but may be made to swing on horizontal pivots for cleaning or other purposes when desired. To attain these ends, the invention consists in the peculiar construction hereinafter described, and then delinitely claimed at the end hereof.

In the accompanying drawings, Figure l shows a horizontal section'of part of a window through both sashes, with the upper sash lowered. Fig. 2 shows a vertical section through the center of the window with both sashes in normal position (closed) in full lines and the sashes in various positions turned in dotted lines. Fig. 3 shows an isometric perspective view of one side of the upper sash with the guide-strip shown moved back and represented as partly broken away. Fig. 4: shows a view of a pivot and hanger. Fig. 5 shows a face view of a plate and screw in position in stile of sash with the guidestrip removed.- Figs. 6 and 7 show horizontal and vertical sections,respectively,through the center of Fig. 5,with the guide-strip shown in dotted lines. view of the screw shown in Figs. 5, 6, and 7. Fig. 9 shows a metal stop in the lower part of the grooves in the pulley-stiles.

Referring now to the details ofthe drawings by letters, A indicates the pulley-stiles, which are provided with three grooves g, g, and h and a rabbet, the latter forming, with the addition of the bead 7c, a groovei similar to the groove h. All of these grooves extend throughout the length otv the pulley-stiles. The stiles Z of the sashes B have strips a applied to their inner sides, which are made to slide sidewise or laterally into the grooves 7L and 1', as shown in full lines in Fig. l and Fig. 8 shows an isometric in dotted lines in Fig. G, and back on the stiles of the sashes, as shown in dotted lines in Fig. 1 and in full lines in Fig. 3.

y To secure and allow the strips a to slide back and forth on the stiles of the sashes, a plate d, Figs. l, 3, 5,'6, and 7, is let into the stiles Z ush with their face in three or more places. The oblong head of a screw e', Figs. 5, 6, and 7, vis introduced into a slot m of the plate d. VHoles yare bored in the strips a (which are grooved on their faces) opposite the screws e in the plates d, when the round screw head or nut c can be secured'on the shank of the screw e in the plates.

The back of the slot m in plates d is beveled toward the center of the sash,as shown in Figs. l and 6, so that the oblong head which holds the screw e and prevents it from turning in the slot m will move readily toward the center of the sash and draw the strip a tight to the stilesl when the strip is moved into the grooves h and z'. The grooved face of the strip a serves to vallow the screw head or nut e to recede back of the face of the strip, which is essential in the case of the upper sash,and also to permit the strip to be grasped -loy the fingers of one or both hands in withdrawing it from the grooves It and t'.

The upper half of the projection of the meeting-rail of the upper sash is cut away, as shown at the lower part of Fig. 3, to allow the strip el to move inwardly. The lower half of the projection, which is close to the stiles of the lower sash, remains to make the sash ltight at that point.

The projection of the meeting-rail of the lower sash :is c ut away entirely to the extent of the movement of the strip a in order to permit this strip ,in the upper sash to be moved in any relative position of the sashes. At the bottom of the lower sash the strip n is secured to the sill o against the insidebead l 7c to ll in the space required bythe sliding strip a, or the bead 7c may be made wider at the bottom vthan on the sides and 'head of frame. Inl either case the strip a is cut off on top of the strips n or k, Fig. 2.

The pivot b, Figs. l, 3, and 4is cast with a groove for the hanger c, and it has a plate b', which is let into the sash-stile Z flush with IOO the wood and secured with screws at the center of gravity. The hanger c, Figs. l, 3, and 4, made of steel wire, is elongated sufficiently to allow it to be sprung onto the pivot b over the projection p, forming the outside of the groove, as shown in dotted lines in Fig. 4. The part of the hanger c on which the pivot revolves may be iiattened out somewhat, if found desirable, in heavy sash. At ff, Fig. 2, are shown metal stops (shown on a larger scale at Fig. 9) which are secured by a screw in the grooves g on both sides of the window just below the pivots in the sashes when they are down, forming a stop on which the pivots rest in turning the sash and keeping it in a horizontal position at the turning-points, preventing wedging. Any other form of a stop may be used for-this purpose.

Then the guide-strips are in their normal position, the sashes slide in the ordinary manner; but if we withdraw the strips a from out of the grooves t' the lower sash can be turned when in its normal position, as shown in dotted lines r, Fig. 2. The upper sash after having been moved downward until the pivots Z1 rest on the stops f and after the lower sash has been moved upward can be turned, as shown in dotted lines s, Fig. 2.

If desired, b oth sashes can be moved simultaneously, as shown in dotted lines t, Fig. 2, or at any other position of height in the frame.

A hanger similar to that here shown is illustrated in my application, Serial No. 625,352, filed February 27, 1897, and no claim is therefore made for it here.

lVhat I claim as new is- The combination in a window of a sash and a guide-strip, with a slotted plate CZ attached to the sash, having the Walls of the slot in the plate increasing in thickness toward the edge of the sash, a screw e' having its head between the plate and the sash, and its shank passing into said strip and the nut e, all arranged substantially as shown and described.

In testimony whereof I affix my signature, in the presence of two Witnesses, this 18th dayof March, 1897.
